I've got a buddy with a violet Spektrum R, and man is it gorgeous in person. I'd love to get an R for a daily driver, it's the only way I can stomach the mk8 -- I'm not a fan of the exterior nor the interior, and looking for an AWD daily that's cheap on maintenance. I'm likely buying a CX-30 though, Soul Red is another color that's very standout IMO and the 2.5 is damn good for an inexpensive to maintain, reasonably reliable engine. And Mazda's interiors have gotten great in the last decade or so.
If I had to choose, Cliff Green or Raspberry Red are definitely in the upper end of Spektrum colors for me.
